From adaa54bdf7a1e0678b6b7fa482407149f589c838 Mon Sep 17 00:00:00 2001 From: Andrzej Kaczmarek Date: Wed, 22 Jan 2014 11:34:44 +0100 Subject: [PATCH] android: Add MTU data to Open Stream Audio IPC MTU value for transport channel is sent in Open Stream response, which is required to calculate number of frames which can be packed into single media packet. This is to avoid including GPLv2 licensed headers in Audio HAL implementation. --- android/a2dp.c | 8 ++++++-- android/audio-msg.h | 1 + 2 files changed, 7 insertions(+), 2 deletions(-) diff --git a/android/a2dp.c b/android/a2dp.c index a996f794e..572e0d120 100644 --- a/android/a2dp.c +++ b/android/a2dp.c @@ -1304,6 +1304,7 @@ static void bt_stream_open(const void *buf, uint16_t len) struct audio_rsp_open_stream *rsp; struct a2dp_setup *setup; int fd; + uint16_t omtu; DBG(""); @@ -1314,14 +1315,17 @@ static void bt_stream_open(const void *buf, uint16_t len) return; } - if (!avdtp_stream_get_transport(setup->stream, &fd, NULL, NULL, NULL)) { + if (!avdtp_stream_get_transport(setup->stream, &fd, NULL, &omtu, + NULL)) { error("avdtp_stream_get_transport: failed"); audio_ipc_send_rsp(AUDIO_OP_OPEN_STREAM, AUDIO_STATUS_FAILED); return; } - len = sizeof(struct audio_preset) + setup->preset->len; + len = sizeof(struct audio_rsp_open_stream) + + sizeof(struct audio_preset) + setup->preset->len; rsp = g_malloc0(len); + rsp->mtu = omtu; rsp->preset->len = setup->preset->len; memcpy(rsp->preset->data, setup->preset->data, setup->preset->len); diff --git a/android/audio-msg.h b/android/audio-msg.h index 8f0327407..17cde097a 100644 --- a/android/audio-msg.h +++ b/android/audio-msg.h @@ -63,6 +63,7 @@ struct audio_cmd_open_stream { } __attribute__((packed)); struct audio_rsp_open_stream { + uint16_t mtu; struct audio_preset preset[0]; } __attribute__((packed)); -- 2.47.3
